Plugin alters look of content in backoffice

Hi

As soon as I activate Multicollab the appearance of some of my post changes. Not on the front end but in the backend. This post displays content in a boxed styled layout. Without Multicollab content is centered. With your plugin activated on the other hand, content spills over onto the sides. Gives a bad impression and makes me wonder about the solidity of the plugin.

Without Multicollab

With Multicollab

Same page on the front end.

Same thing happens for other content types using the boxed style layout.

Kind regards
